< Caution > In case of low-voltage circuit, secondary side earthing of VT and CT is unnecessary.
And, VT is unnecessary in case it used direct 110V.
■ Cautions on connections
Please do connection of the wiring correctly with reference to the upper connecting diagram.
In the case of the DC power supply, it is S1(＋) and S2(－).
Even in case the output of a transducer is sent to a direct distant place and there is a possibility of receiving
the influence of indirect-stroke serge etc. in a transmission line, because the protection network is built in
this product, the protection by the side of this product output is unnecessary.
In addition, in order to protect the apparatus by the side of a receiver, please install an about 500V arrester
etc. to a receiver side between the serge protector between wires, and a transmission line and the ground.

3.6 Handling explanation

The usage of this product should perform the right usage with careful attention to the following item.
(1) Please check that the voltage of power supply and the input signal to supply match the specification of this
product before power-supply applying.
(2) Please confirm that wiring is connected to the terminal position as specification (Indicate on name plate).
(3) Please use output load by name plate display load resistance value within the limits. It not only becomes a
mistaken output, but impose a burden on this product in case it is used other than a display load resistance
value. Please avoid especially the output short circuit in a voltage output.
About a current output, even if it uses it by output open, this product is not damaged.
(However, in current output open, about 15V terminal voltage occurs.)
(4) The range that output adjustment is possible.
BIAS：±5％ of the output span.
MAX ：±5％ of the output span.
In order to make it match with a connection device, please use it, only in case adjustment is needed.
(5) Please keep noise source away from wiring.
(6) Inrush current flows in power-up. Please pay attention to over-current protection of power supply to use.
Please refer to the 2.4th section about current value.
(7) An output may appear also in few time at the case of power-supply ON / OFF (an input is 0).
(8) The output (-) terminal of each factor is electrically common inside.
(9) Please set the grounding resistance of a earth terminal (E) to 100Ω or less.
(10) Please use it altitude of 2000m or less.
